It's been an interesting year in technology. Nintendo invented a video game you control with a magic wand. A new kind of car traveled 3,145 miles on a single gallon of gas. A robot learned to ride a bike and somebody came up with a nanofabric umbrella that doesn't stay wet

Hydrogen Bomber

It may be years before you can buy a Chevy powered by hydrogen fuel cells. Tired of waiting, Shanghai-based Horizon Fuel Cell Technologies decided to design and market the H-racer, a 6-in.-long toy car that does what Detroit still can't. It runs on hydrogen extracted from plain tap water using the solar-powered Hydrogen Station, below, and can travel more than 300 ft. in a single fuel-up. The car's miniature scale gives it one advantage over full-size prototypes: since it uses only a trace amount of flammable hydrogen, there's no risk of it pulling a Hindenburg in your living room.
